STORAGE
3. With the mower in an upright position, open the clip director, start
the engine outdoors, engage the blade control lever, and let the
engine run until it reaches normal operating temperature to
evaporate any water remaining on the engine.
4. Stop the engine and allow it to cool.
5. After the lawn mower is clean and dry, touch up any damaged
paint (touch-up paint part numbers are on page 73), and coat other
areas that may rust with a light film of oil. Lubricate the control
cable cores with a silicone spray lubricant (page 73).
Charging the Battery (HMA type only)
To assure maximum reliability, the battery should be recharged (boost
charged) both before and after prolonged storage. A plug-in charger is
provided to recharge the battery (see page 50).
NOTICE
Do not charge the battery for more than 24 hours or the battery may be
damaged. Disconnect the battery charger from the battery before
storing the lawn mower.
